Patio doors have become a preferred way of beautifying and extending many homes in Britain.

They flood interior spaces with natural light and provide convenient access to external areas in stylish ways. A few years ago, having patio doors fitted wasn’t such an attractive option. There were problems with poor security and high levels of energy inefficiency, largely due to the materials available at the time.

Modern technology has found its way into all parts of materials manufacturing.

This has improved on everything from the materials used for the frame to the glass used. Materials like aluminium are used to make these doors very light in weight, yet very strong and durable.

Other doors are made with vinyl or fibreglass which can be treated to look and feel like wood, but without the high maintenance required of wood. A popular choice is steel. Steel bi-fold patio doors are the most economical to construct. They are strong and durable; and can withstand the fluctuations of most climates. They are also low maintenance requiring very minor upkeep.

With soaring energy prices, it is important to reduce costs where ever you can.

One way to do this is to conserve as much warmth in the house as possible. The kind of glass used in constructing your doors will determine how energy efficient they will be. By helping to reduce energy costs, the right patio doors will pay for themselves.

Looking on the Internet for information regarding choosing a door can lead to a few bouts of migraine. Industry experts spout terms and numbers expecting you to know what they mean. Forums offer a plethora of fishy information. The experts at SRL Ltd will walk you through every step of the process of understanding the types of glass and patio doors available.

With energy efficiency for glass and glazing, there are many factors to consider; such as the:

  • U-factor – The rate at which a window, door, or skylight conducts non-solar heat flow. This measures how much heat you lose from a room through the patio door glass.
  • Solar Heat Gain Coefficient (SHGC) – the fraction of solar radiation admitted through a window, door, or skylight
  • Air Leakage‚Ä® – The rate of air movement around a window, door, or skylight in the presence of a specific pressure difference across it.
  • Sunlight Transmittance – The ability of glazing in a window, door, or skylight to transmit sunlight into a home.

Other key metrics include Visible Transmittance (VT), Light-to-solar gain (LSG). More determinants of energy efficiency levels include whether you choose to get Low-E glass, Softcoat or Hardcoat. Are you going to buy UV coated glass to reduce the amount of heat that passes through the glass? Would you like glass that darkens with the intensity of the sun?

All these factors are inter-related and have an impact on how much you will enjoy your doors.

Attempting to understand them all and make the decision is going to cost you time and money. Contact the experts at SRL Limited and let’s translate these technical terms into the most important thing; your comfort.
